(Ci. H3-116) 4 Claims.

This invention relates to hose connectors, and more particularly to amethod of making a clincher hose mender or coupling which may be used to readily connect two sections of hose.

This application is a division of our prior epplication, Serial No. 617,784, led June 17, 1932, for Hose couplings, and which will issue on July 25, 1933, as Patent No. 1,919,860. The invention is an improvement over Patent No. 1,321,323 to Nelson granted November 11, 1919.

One object of the present invention is to provide a hose clincher, coupling or mender of the above nature comprising a pair of clincher hose engaging members, assembled back to back upon a tubular formed blank, the latter having portions expanded outwardly against said clincher members for rigidly securing theparts together.

A further object is to provide a hose clincher coupling or mender of the above nature in which the tubular blank is provided with three outwardly extending ring sections or beads forced into Contact with said clincher members, whereby said members will be positively held against rotative or longitudinal movements. i

A further object is to provide a hose coupling of the above nature which will be simple in construction, inexpensive to manufacture, easy to install and manipulate, compact, ornamental in appearance, and very efficient and durable in use.

` With these and other objects in view there have been illustrated on the accompanying drawing, one form in which the invention may be conveniently embodied in practice.

In the drawing:

Fig. 1 represents a perspective view of the clincher hose coupling or mender.

Fig. 2 is a longitudinal sectional view of the same.

Fig. 3 is a vertical sectional view of the die apparatus used in manufacturing the clincherv hose couplings or menders, the parts beingshown in their relative positions just prior to the forming operation.

Fig. 4 is a fragmentary sectional view of a portion of the forming dies and the mender after the forming operation has been completed.

Referring now to the drawing in which like reference numerals denote corresponding parts throughout the several views, the numeral I0 indicates a formed tubular blank which comprises the central connecting member in the completed Surrounding the middle section of the clincher members II and I2 having a pair of oppositely disposed interior collars I3 and I4 which are adapted to slip loosely over the outside periph.- ery of a smooth tubular blank Ida as shown in 3. The clincher members II and I2 are formed with a plurality of outwardly inclined fingers or lugs l5 and I6 having inturned outer pointed ends forming spurs Il' and il, which are adaptedto bite into a hose, not shown, when said lingers i5 and iii are hammered inwardly against the hose.

In order to permanently secure the juxtaposed clincher members II and I2 upon the tubular blank ida in such a manner as to prevent relative longitudinal sliding of saidparts, the blank is adapted to be expanded or buckled outwardly to form three rings or beads I9, 29 and 2 I, as shown in Figs. 2 and 4, said beads being formed on the outside and inside oi said clincher member collars i3 and I4. 4Moreover, the central apertures in said collars i 3 and I4 are preferably made slightly out-oferound or ovalized so as to positively lock the clincher members Il and I2 against rotation upon said blank I0.

The outer ends of the blank lo are pro-vided with a pair of enlarged conical beads 22 and 23 having inwardly converging extremities 25 and 25 which are adapted to be inserted within the hose to be connected.

The process of assembling the relative parts of the hose clincher coupling or mender is illustrated by the apparatus shown in Fig. 3 by means of which the smooth tubular blank Illa and the two hose clincher members I E and l2 are adapted to `be assembled. Figs. 2 and 4 show the appearance of the completed hose coupling.

Referring to Fig. 3, the numeral 26 indicates a lower die or anvil supported within a stationary die bed 2l. The anvil 26 is provided with a vertical post or mandrel 28 over which the original smooth tubular blank ia may be readily slipped and seated within a circular socket 29 formed in the upper part of the anvil 2S. A sliding sleeve 3B is fitted around said anvil 26 and is adapted to be supported upon a plurality of helical com-- pression springs 3|, and said sleeve 30 may be encased within an inverted cup-shaped member 32 secured to the die bed 2l, as by screws 33.

Located above and in axial alinement with the stationary anvil 26 is an upper reciprocating die 34 having a central bore 35 slidably tted over the mandrel 28. The lower part of the central bore 35 is formed with an annular recess 36 adapted to iit over the upper part of the tubular blank Illa. The upper die 34 is also provided with a sliding sleeve 31 which is adapted to be com pressed against a plurality of helical springs 38 encased in sockets 3S formed in said die Si.

The sliding sleeve 37 is adapted to be held in place at the lower end o the die 3d by means of a pair of plates ll and il secured to the opposite sides of said die, 'as by screws 32. The lower edges of the plates d and di are provided with inturned anges 43 and id against which the sliding sleeve is adapted to engage and be held in operating position.

Operation In operation, the process oi assembling a clincher hose coupling is as follows:

The tubular blank ld will first be slipped over the vertical mandrel 8 and seated within the circular socket 29 formed in the lower anvil 26. The two clincher members il and i2 will next be loosely assembled upon the blank iii@ and supported by means of the lower` sliding sleeve 30.

VThe upper die 355 will then be caused to descend and move to the position shown in Fig. 3, whereupon the ends of the tubular blank iia will be abut-ted against shoulders di and d8 formed at the ends of the recesses 3E and 1229 in the upper and lower dies 35 and 2t respectively. As the die 34 continues to descend, the tubular blank iiia will be caused to expand or buckle outwardly forming three locking beads ii, 2Q and 2 i, as clearly shown in Figs. 2 and i.

It will be understood that since the center apertures in the clincher members il and l2 are made slightly non-circular or ovalized, the metal in the tubular blank lila will be expanded into contact with said apertures so as to produce a positive locking engagement therewith. When the clincher members il and i2 have been assembled to the blank iii by the above described method, the upper die 'Sil will then be retracted and the formed tubular blank l removed from the mandrel by any mechanism, not shown. lThe ends of the blank i@ will be finally headed into the conical shape shown in Figs. l and 2 by y mechanism not shown.

is claimed as new, and for which it is desired t secure Letters Patent, is:

1. The method of making a clincher hose coupling which comprises inserting a mandrel snugly with a tubular connecting metal member, applying a pair of clincher members around said connecting member, whereby said connecting member will be supported at a pair of circumferential lines spaced along its length and on the outside thereof, and upsetting the metal of said connecting member outwardly both between and outside said lines, and thereby forming three outwardly extending beads which serve to prevent relative longitudinal movement between said tubular member and said clincher member.

2. The method of making a clincher hose coupling which comprise-s inserting a mandrel snugly within a tubular metal connecting member, applying a pair of clincher members around said connecting member whereby said connecting member will be supported at a pair of circumferential lines, and upsetting the metal of said connecting member outwardly both between and outside said lines by pressing the ends of said connecting member toward each other in a longitudinal direction to form a plurality of outwardly eX- tending beads which serve to prevent relative longitudinal movement between said tubular member and said clincher members.

3. IThe method of making a clincher hose coupling which comprises tting a mandrel within a metal tube, applying aA clincher member around said tube for supporting said tube along a. circumferential line, and upsetting the metal of said tube outwardly at both sides of said line by pressing the ends oi said tube inwardly toward each other in a longitudinal direction to form a pair of outwardly extending beads which serve to prevent relative longitudinal movement between said tubular member and said clincher member.

4. The method of making a clincher hose coupling which comprises fitting a mandrel within a metal tube, applying a pair of hose engaging members having eccentric central apertures around. said tube for supporting said tube at a pair of circumferential lines spaced along its length, and upsetting the metal of said tube outwardly both between and outside said lines against the edges of the apertures of said hose engaging members to form three outwardly extending locking beads which serve to prevent relative longitudinal movement between said tube and said hose engaging members.
